HA17800V/VP/VPJ Series
3-terminal Fixed Voltage Regulators
Description
HA17800V series is positive output 1 A three-terminal regulator IC. Which features are as follows. It is
designed to suit to the power supply of various equipments and to stabilize the multi switching regulator
voltage, and to supply power to some kind of control devices.
Features
•
High ripple rejection ratio up to high frequency
(f 20 kHz): 60 dB(in the case of HA17805V/VP/VPJ)
Protected against oscillation
•
•
Regulated output voltage against temperature
(0 Ta 125°C, 80 ppm/°C typ)
•
•
Hard to breakdown against irrelevant connection
Built–in circuits as over current control circuit, temperature protection circuit, and area of safety
operation control circuit
